Netflix's Dept. Q season 2: potential release date, plot, and the cast lineup

Well, look at that – Netflix actually stuck this one out rather than dumping it after a single season (which is turning into their trademark move lately). 'Dept. Q' is coming back for Season 2, so fans of twisty cold cases and dour Scottish police basements can breathe easy for now.

Yes, It's Official: Season 2 Is Happening

The green light came on 18 August 2025, complete with a self-deprecating victory lap from series lead Matthew Goode. To absolutely nobody's surprise, Goode seemed chuffed to be back solving crimes as the irascible DCI Carl Mørck. In what is basically the most polite British flex possible, he said:

'I’d like to thank Netflix for giving us the opportunity to further investigate Dept. Q’s storylines. We have a wonderful cast and crew, headed by our resident genius Scott Frank [the series’ creator]. I cannot wait to read what comes from his magic quill!'

So he’s clearly enjoying himself. And honestly, you can see why – while Netflix has a reputation for swinging the axe, this Danish-to-Edinburgh adaptation has a strong devoted following, thanks in no small part to Goode’s turn as Mørck: charming, miserable, borderline insufferable – just how we like our TV detectives.

What Actually Happens in 'Dept. Q'?

Just to bring everyone up to speed – 'Dept. Q' is based on the Jussi Adler-Olsen novels and plonks us right in the basement of a Scottish police station, where misfit detective Carl Mørck is leading his equally oddball team through long-abandoned, unsolvable cases. Instead of wall-to-wall gloom, the show sprinkles in a fair bit of dark humour (very Scottish, that), and there’s a solid mix of character work beneath all the icy cold cases.

The balance is not easy: you get both the tangled mysteries themselves and the self-sabotaging, emotionally stunted people digging through them. That combination is probably why the first season hit a note with fans who like their crime a little off-kilter – and not afraid of the odd embarrassing workplace breakdown.

Who’s Actually Coming Back?

We don’t know everything yet – filming doesn’t start until summer 2026 – but here’s where we stand:

• Matthew Goode returns as grumpy Detective Chief Inspector Carl Mørck
• Leah Byrne reprises Rose, always keeping Mørck honest (or at least legally sound)
• Alexej Manvelov is back as Akram Salim, still eminently more sensible than anyone else in the room
• Jamie Sives returns as James Hardy

That’s the core squad for now. No word yet on the rest – and with a new case up next, there’ll be a fresh line-up of suspects/victims/lurkers coming once production gears up.

On the creative side, Scott Frank (who created and steered Season 1 with Chandni Lakhani) is back to write and direct, adding his usual dry wit to the press rounds. Apparently, his commitment to risking everyone’s reputation remains unsullied:

'I’m grateful to the folks at Netflix, as well as our shining cast and crew, for once more risking their careers to enable my folly.'

The rest of the creative crowd includes producers Rob Bullock and Charlotte Moore, plus Netflix execs Mona Qureshi and Manda Levin keeping a sharp eye on proceedings. The business end stays the same: Left Bank Pictures produces, working with Sony Pictures Television.

Bullock chimed in with his own wink to the controlled chaos:

'So, we are going downstairs to Dept. Q for a second season. We at Left Bank Pictures nervously await what Scott has in store for his alter-ego Carl Morck, and the other enabling members of team do-lally. We salute Netflix’s courage to let them loose once again.'

It's all sounding remarkably upbeat for a show about murder cases.

What’s Next for the Story?

Scott Frank made no secret that Season 1’s ending deliberately left a door open for more, should Netflix play nice. Now he can actually pull from Adler-Olsen’s second novel, 'The Absent One,' for the Season 2 arc.

Just for clarity: Frank told Collider he reckons the next season will tackle a new old case – and a current one simultaneously – and he might cut the episode order from nine to six. He’s got a plan, basically, but isn’t declaring a final episode count yet.

'The second book in the series is quite good, so I’ve got a great idea for a second season. It is another cold case and also a current case, at the same time, that they’re looking into. So, I would do that. I don’t know that I would necessarily do nine episodes. I might just do six next time. We’ll see. But I do know what I want to do next. I do have the story in mind for the next season.'

Here’s the other thing: Season 1 wrapped up its main cold cases, but there’s one major hanging thread – the Leith Park shooting that left Carl and Hardy with new holes. Still no word on who pulled the trigger, and Mørck’s convinced it wasn’t just some random nutter. That storyline’s expected to snake its way through the next lot of episodes, so expect that unresolved itch to get scratched (or picked at, knowing this show).

If you want a quick sense of where the books go: the second novel drags up a two-decades-old double murder – brother and sister – that seemingly got wrapped up with a boarding-school golden boy behind bars. Mørck pokes at the files and, predictably, it all falls apart, dragging him off in pursuit of a fugitive called Kimmie who knows far too much about powerful people (and is barely staying ahead of the police herself). Will the series stick tight to the book? That is, as always, up for grabs.

And if the Netflix series keeps ticking, there’s no shortage of material – Adler-Olsen’s written ten of these, so conceivable seasons stretch well into the next decade.

When Will We Actually See Season 2?

Don’t hold your breath. While there’s no official date yet, it’s pretty clear we won’t get any footage this side of 2027. Filming’s booked in Edinburgh starting 13 July 2026, running until mid-December – so, realistically, add post-production and all that jazz and you’re looking at the back end of 2027 before anything hits screens. Far cry from the earlier whispers of a 2026 launch, but, honestly, these days that’s par for the course.
